'Lost' in the Bible

"For this is how God loved the world: He gave his unique Son so that everyone who believes in him would not be lost but have eternal life.

When they were filled, he said unto his disciples, Gather up the fragments that remain, that nothing be lost.

Many of them were saying, "He is possessed by a demon and has lost his mind! Why do you listen to him?"

I give them eternal life, they'll never be lost, and no one will snatch them out of my hand.

While you have the Light, believe and trust in the Light [have faith in it, hold on to it, rely on it], so that you may become sons of Light [being filled with Light as followers of God].”Jesus said these things, and then He left and hid Himself from them.

While I was with them in the world, I kept them in thy name: those that thou gavest me I have kept, and none of them is lost, but the son of perdition; that the scripture might be fulfilled.

That the saying might be fulfilled, which he spake, Of them which thou gavest me have I lost none.
